This invention relates to journal boxes and comprises all the featuresof novelty herein disclosed. Anfob'ect of the inventlonis to provideVimprove lubricating circulating '3j means for shaft bearings. Anotherobject is to provide improved devices for distributing the wearoccasioned byinduced end thrusts of an antifriction bearingV audits cageand for conveying lubricant to andfrom the bearings.

10 To these ends and to im rove generally and selected for illustrationin the accompanyingdrawings in which p F'g. 1 isa longitudinal verticalsection of an axle box.

' zo mg. 21s n perspective new or the nner Big. 4 is a section on theline 4-'4 of Fig. 1.

- Fig. 5 a perspective view of the inneroatmg ring.

The numeral 6 indicates'a shaft or axle having stepped cylindricalsurfaces 8 and 10, a sleeve 12 in shrunk or pressed on the surface 10and he d by a split ring 14 which is placed in a ove of the axle. One ormore sets of anti iction bearingscomprising rollers 16 having end ringsor cages 18 are inter-V posed between the sleeve 12 and a lining 20mserted in the bore of an .axle box or vcasing 22. The box has anout-turned flange -24-to`which an end cap26 is secured Yby nuts andthreaded studs 28, the inner ends' of the studs being threaded in andwelded t0 4 the an e as indicated at 30 to prevent loosening. T e endcap has a lu 32 extended inwardly into a slot formed y spaced 'cheeks 34near the topl of a retaining ring 36 to hold the ring from turning. Theretaining ring has'a square opening 37- for the square portion of abrass thrust block' 38 .and spacin plates 40, the block and plates beingclamps against Ythe end cap by a bolt 42 and nut 44. The bolt has squarecollars 46 on which the Vthrust block is cast to hold the bolt fromoccasioned by induced end thrusts of the bearturning. 'The inner fnnn nfare unna block opposes theend v'face' of the axle which is lubricatedbya wick 48 extendin from a lubri.-

cant reservoir v 50 inthe box, t ough a boss i or extension 52V on theretaining Aring to va recess 54 in yun. thrust block. j The extension 5l 52, in conjunction'with an internal projection 55 forms a deep supportor holder for the wick. Oil is admitted to the box through a hollow bosson the' endcap' and, after 66 lubricating the end'of theal e, collectson a rib 62- and isf-thrown, oil' lnto an annular groove 64.v one wallofwhich is formed by an vinwardly extendin abutment flange 66. .The

lower part ofthe ange 66 is cut throu h or 65- l notched at 68 Ato admitlubricant to the earings as will appear. v The retaining rin 36 has aretaining ange V70 externally prov1detl with grease grooves l y to makea close joint withlthe bore vof thefbox 70 and so partition oii the axleand bearings from the reservoir. The abutment ilan e 66 has a groove 7 2uand between the flan e an the cage 18 is interposed a oating ring 4having its 'periphery formed with vcross slots. or scallops 76 to admitoil from'the notch 68 to the bearings. The ringy is preferably bronzeandy has its corners chamfered as indicated in def' tail at 78 in Fig.2. -The ringtakes the wear ings, 'and the cross .slots or scallops 76are spaced near'enough together to rinsure that one or more of `themwill bein communication -with the notch 68 in every position of thering.

The ring is free vto rotate or float by"l rubbing 'contact with the cageand so will act to distribute wear and to lift oil yas it turns on thesupport afforded by Ilthe inner Wall of the flange ZO. The rin thusvcarries oil which lubricates its side aces and peripheryand this oilmust traverse `the bearings before returning to the reservoiras willappear.

The inner or rear end of the box has an inwardlyv extending retainingand abutment ange 82 providedv with grease grooves making a close jointwith the surface 8 of the axle. Between anv abtument surface 83 of theange and the 'nearest end'ring or cage^18 is inter posed a secondfloating 'rin-'g 84 supported peripherally by the inner 'cylindricalsurface 86A les of -a projecting ange or rib which, howe ver, shaft, ajournal box, an antifriction bearing is cut through or notched 4(top andbottom) at 88 and 90, the lower notch 90 admitting oil to a space 92from which the oil returns to the reservoir for further circulationthrough an v inclined drain passage or core 94. Oil which may work alongthe shaft is arrested by a rib 96 and groove 98 and is thrown olf intoan an-V nular groove 99 formed by a portion of the retaining flange 82and by an inwardly ex-l tending annular {iange 100 on the floating ring84. The oil then passes through one or more radial slots 102 cut in theside of the floating ring, the slots being suiiiciently close togetherto insure one'or more being always in communication with lthe notch 90.The

v projections 104 between the slots lift suiicient oil to lubricate theside faces and periphery of the ring. The outer corner of the floatingring is chainfered as indicated at `106 to allow oil from the bearingsto drop into the slot 90.
